Leachco Podster to prevent flat spot?

[Hopeful8289]

So I have a podster to help with my baby's spitting up and give him a comfy spot to sit while I do things and now I'm wondering if using it has helped prevent flat spots for anyone? I have started to notice he favors laying with his head to the left when he sleeps and it already looks flatter. I want to figure out where I can place him some throughout the day that won't worsen the flat spot. Anyone have any experience with the podster? Any other suggestions?
